Based on the established GIS of the Oncomcelania Snails' distribution in Dongting Lake, the author analyzes the environmental condition of the Oncomcelania Snails' habitates comprehensively by the spatial analyzing technology. The results are as following: firstly, the predominant vegetation of Oncomcelania Snails habitat is reed and sedgy. The habitats with reed has a higher livability than with sedgy as dominating vegetation. However, the diffusion of Oncomcelania Snails is much serious in the habitats with sedgy. Secondly ,the predominant soil type of the Oncomcelania Snails breeding area is temporary submergic paddy soils, which is in weak acidity environment, of that PH value is 5.5--7.5, and the organic content is in 2---3%. Thirdly, the 80 percent of the Oncomcelania Snails breeding area, the normalized difference vegetation index of that is in 0.100-0.375%, and the soil humidity of that is in 0.202—0.507, and the distance to the water of that is in 10-230 meters.
